If you keep a few bottles of perfume or cologne around the house, but don't use them that often, consider storing them in a box in your closet to keep them from going bad.

Kristin Appenbrink at Real Simple warns us that heat and light can alter the scent of your fragrances, so it's best to keep them in cool, dark environments. Out in the open, perfumes and colognes will still last several months, so this isn't a huge deal if you use them often and go through a bottle fairly quickly. If you only break out fragrances for special occasions though, this tip will maintain the proper scent for well over a year, meaning you won't have to rush out to replace it on the one night you really needed it.
